What is Dify?

Dify is an open-source platform designed to help developers build, deploy, and manage applications powered by large language models. It provides a visual interface for creating AI workflows without requiring extensive coding, along with tools for prompt management, model orchestration, and data integration. The platform is built for both individuals prototyping AI features and teams running production applications. Dify combines a no-code builder with backend APIs and monitoring tools, making it suitable for creating chatbots, content generation systems, search tools, and custom AI agents. Because it's open-source, you can self-host it or use their managed cloud version, giving you control over data and deployment options.

Pros & cons

Advantages

  • Open-source codebase means you can self-host and modify the platform to suit your needs
  • No coding required for basic workflows, making it accessible to non-technical team members
  • Good balance of ease-of-use and technical depth for both prototypes and production systems
  • Built-in RAG capabilities reduce the need for third-party vector database integrations

Limitations

  • Smaller community and ecosystem compared to closed-source alternatives, so fewer plugins and integrations available
  • Self-hosting requires technical knowledge and infrastructure management if you want to avoid the managed service
  • Documentation and learning resources are still developing as the project matures

Use cases

Building customer support chatbots that reference your company's documentation and knowledge base

Creating content generation tools for marketing teams using your brand guidelines and past examples

Developing internal search tools that find answers from your organisation's documents

Prototyping AI features before building them into your main application

Running multi-step workflows that coordinate between different LLMs and data sources
